ABSTRACT:
An X-ray tube has a cathode and an anode arranged in a vacuum housing, the electron beam emanating from the cathode proceeding through a hollow cylindrical housing part of the vacuum housing to the anode. An electromagnet is provided for the deflection of the electron beam. The electromagnet has a U-shaped yoke with two legs having first ends connected to one another by a base section and having a winding surrounding the base section. The legs straddle the housing part and the electromagnet is disposed so that the electron beam is spaced a distance from the second ends of the legs so that from the second ends of the legs so that the electron beam is situated only in the stray field of the electromagnet, rather than in the region of maximum field strength.
